Why is Knob & Tube Wiring Considered Dangerous?

• Age of wiring

  Knob & tube wiring was used up until the 1940's. Today's modern appliances and electronics consume more electricity and if you still have outdated knob and tube wiring, you are running the risk of overloading the wiring which can cause an electrical fire.

• Insulation

  Insulation was typically installed over the knob & tube wiring which increases the risk of fire. This extra layer of rubber cloth insulation has minimal space to disperse heat that builds up as current flows through the wires.

• Alterations & Repairs

  We see quite a few issues with knob & tube wiring that were due to DIY fixes or untrained handymen. These old systems are challenging to find parts for which often leads to band-aid solutions and improper alterations.

• Absence of Ground Wire

  Knob & tube wiring does not have a ground wire (two-pronged outlet) which makes it unsafe for modern three-pronged appliances and electronics.

• Moisture

  Aluminum knob & tube wiring is not suitable for moist environments. Areas that have been exposed to moisture can be dangerous and a shocking hazard.
